I have not bedded any of my sidelocks. But I've often thought of doing so because I have experienced POI shift after removing the barrel from the stock for cleaning. Sometimes, not every time but sometimes, I need to make sight adjustments after restoring the barrel to the stock. I suspect the type of two point bedding
MountainDevil shows above would fix that.
I also wonder whether a good bedding job would fix my "1 in 5" flyer problem.
